I make the cutout on my Silhouette and then place it on the dish. I use etching cream from Hobby Lobby. I dab it on with a small foam brush. It only takes 5 minutes to set. Wash it well before removing the vinyl, and you're good to go.
video tutorial on how I used got my Silhouette to recognize a png file and then use the print and cut feature to cut it out.
I loooooved the colors of this set, so I decided to make a mini set using similar shades. You can find it in my TPT store.
